I am unable to reach anyone at my local branch in Sonora regarding a ruined piece of artwork for a shop. I've got photographs of the damage done, it made it to buyer but part of it was torn and taken, and the mailing tube was sawed through and then retaped. It's beyond heinous to do this, and it hurts my business (and livelihood). This post office has surly, rude and downright disrespectful and unhelpful employees. I cannot understand why and how this could have happened.


PO box access hours are posted open 24 hours. But at 7am the doors were locked. Great customer service Sonora USPS.
